Nicki Minaj is currently filming her on-screen debut "The Other Woman (2014)". The latest on-set pictures captured on May 23 see the "Pound the Alarm" rapper donning a black straight wig and hiding her costume behind a velvet blue dressing gown for her role as Cameron Diaz's opinionated and honest assistant.

Minaj has been spotted wearing three different wigs on the filming location, which takes place in Manhattan. The Harajuku Barbie previously rocked luxurious Rapunzel-alike curls and a raven straight wig with fringe. "Lmao. Yall r so silly. In the makeup chair now. Getting ready for the next scene. Aaaaahhhh!!!!" she recently tweeted.

The upcoming film is from "The Notebook" helmer Nick Cassavetes, centering on Diaz's character who finds out that her boyfriend is already married. Trying to get back at him, she allies herself with his wife and another mistress.
